MLS Power Rankings, Week 29: Who's in and out

Three of 10 Major League Soccer postseason slots have been filled, only one team is out of contention, and the regular season heads into its final four weeks, we could be treated the the greatest race in league history.

Not at the top, where it'll take something wholly unexpected to keep the Galaxy from successive Supporters' Shields. Only Seattle and Real Salt Lake can catch L.A., and last week both clinched playoff berths to join the Western leader.

The battle for the Eastern Conference title, the East's three automatic postseason berths and the four wild-card slots is going to be fantastic.

The top six teams in the East are separated by four points, with first-place Houston just a point in front of Sporting Kansas City and Columbus, which meet Wednesday night looking to overtake the Dynamo.

Eight teams fighting for six postseason berths -- figuring FC Dallas' 46 will be enough if it can't reverse its slide -- are separated by five points, and Chicago's ceiling throws it into that group, too.

Only Vancouver has been eliminated, but New England and Toronto figure to join them this week, and Chivas USA ought not survive much longer, either.
